Effect of preoperative analgesics and cooled Lidocaine with Epinephrine on the anesthetic efficacy of inferior alveolar nerve block in patients with symptomatic irreversible pulpitis: A single-blind, randomized controlled trial [PDF]

Background: Treating mandibular molars with symptomatic irreversible pulpitis poses challenges, as achieving anaesthesia in “hot teeth” is difficult. Epinephrine aids anaesthesia by reducing blood absorption through local vasoconstriction.

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations

Advanced Functional Materials, EarlyView.
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.

Bacteria‐Derived Extracellular Vesicle as A “Trojan Horse” for Selective M1 Macrophage‐Targeting in A Multi‐Cellular Entanglement Environment

Advanced Functional Materials, EarlyView.
The temporary transition of macrophages from a pro‐inflammatory phenotype of macrophages (M1) to an anti‐inflammatory phenotype of macrophages (M2) is crucial for tissue repair and regeneration processes. Bacterial outer membrane vesicles (OMVs) are utilized as a “trojan horse” for specific M1 macrophage‐targeting and anti‐inflammatory drug delivery ...

Crystal Structure Studies of Human Dental Apatite as a Function of Age [PDF]

arXiv, 2008
Studies of the average crystal structure properties of human dental apatite as a function of the tooth-age in the range of 5-87 years are reported. The crystallinity of the dental hydroxyapatite decreases with the tooth-age. The a-lattice constant that is associated with the carbonate content in carbonate apatite decreases with the tooth-age in a ...
